Line chart with 2 colors or 2 chart in same place

[Paulo]

I have a graphic. In this graphic I need to show two moments. One moment, between a year range and other moment in other range. So, each range must be two diferent colors, in same line serie. I think to build two series, but when I put serie = 0, I heve a dot line, but I don't want a dot line, but invisible line. Is posible? Below my code:

chartSeries1.SetValues(bl.doubleArrayMercado);
chartSeries2.SetValues(bl.doubleArray2009);
chartSeries3.SetValues(bl.doubleArray2010);
for (int i = 0; i < bl.doubleArray2009.Length; i++)
{
if (bl.doubleArray2009[i] == 0)
{
chartSeries2.Items[i].Empty = true; //Here a dot line and no invisible line 

chartSeries2.Items[i].Visible = false;
}
}
for (int i = 0; i < bl.doubleArray2010.Length; i++)
{
   if (bl.doubleArray2010[i] == 0)
   {
chartSeries3.Items[i].Empty = true;//Here a dot line and no invisible line
chartSeries3.Items[i].Visible = false;
    }
}

Hello,

You have complete control over the visual style of empty values. Hiding the dot line that appears can be achieved by setting the EmptyValue line color to transparent like this:

chartSeries2.Appearance.EmptyValue.Line.Color = System.Drawing.Color.Transparent;

Hope this helps.
